  • Patent number: 11109505
    Abstract: A locating device includes a guiding member, a sliding member and a pulling assembly. The guiding member includes a guiding channel inwardly cut through a top thereof, and the sliding member has side plates which each has a locating part. The pulling assembly comprises a pulling body having a guiding element, a fastening element disposed on a side thereof opposite to the guiding element. When the pulling body is in an open state, the fastening element is not located on the locating part; when the pulling body performs a locking operation, the guiding element is slid in the guiding channel and the sliding member is simultaneously slid in another direction opposite to the guiding element; when the pulling body is in a locked state, the fastening element is located on the locating part. Therefore, operational difficulty can be reduced and assembly speed can be improved.

  • Patent number: 11018452
    Abstract: A positioning fastener includes a base having a seat plate extended therefrom, a fixing portion disposed below the base for fastening to an electronic substrate, and an elastic positioning structure disposed above the base and including an urging plate, a pressing plate connected to the urging plate, a positioning space defined therein and a positioning member disposed at a bottom side thereof. The urging plate and the pressing plate are squeezed backwards and elastically deformed by a circuit board that is rotated downward so that the circuit board passes the urging plate and moves into the positioning space of the elastic positioning structure and a suspended board edge of the circuit board is secured in position by the positioning member. The pressing plate can be pressed by an external force to lift the urging plate, allowing the circuit board to be rotated in direction away from the positioning member.

  • Publication number: 20210102566
    Abstract: Board member fastener used to rivet first board member and second board member. First and second board members each have drilled therein a different diameter of hole. First board member provides first through hole. Second board member provides second through hole. Top of first through hole of first board member is formed with stop surface that tapers toward outer diameter so that when board member fastener is punch impacted, board member fastener sinks into interior of first through hole to cut second board member and to deform, and first board member is forced by sinking stress of board member fastener and tightly pressed on second board member upon punch impact, and thus, board member fastener, first board member and second board member are deformed and fitted to each other, achieving a riveting structure that can be applied to different materials and can overcome deformation caused by heat expansion and contraction.
